A mobile body positioning station and a mobile body positioning system include a first partition, a second partition disposed along a direction intersecting an extending direction of the first partition, and a guide device as a guide disposed on a movement path of a robot as a mobile body. The guide device is disposed along an oblique direction with respect to the direction perpendicular to the extending direction of the first partition to extend from the first partition toward the second partition side. The guide device is configured to make the robot move in the oblique direction more easily than move in directions other than the oblique direction, and the guide device moves the robot along the first partition toward the second partition.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

A tie-down secures a load onto a vehicle. The tie-down has a pivot, and a winch. The pivot has a pin, a rotatable sleeve, a cap, and a base. The pin is an annular tube. The winch has a U-shaped frame comprising first and second walls, and a third wall interconnecting the first and second walls. Flanges attach the first and second walls, respectively, of the winch to the sleeve. The third wall is perpendicular to the sleeve. The vehicle has a support surface for supporting the load, and a plurality of the tie-downs. The tie-downs comprise left-hand tie-downs and right-hand tie-downs. The tie-downs are attached to shelves attached to the vehicle adjacent and extending away from the support surface. The shelves comprise left-hand shelves and right-hand shelves. Alternatively, anchors are attached to the tie-downs for removably mounting the tie-downs within stake pockets of the vehicle.

A gripper includes at least one first gripper finger adjustably mounted to a gripper main body by a gripping finger mount, at least one second gripper finger cooperating with the first gripper finger, and a motor-drivable transmission configured to adjust the at least one first gripper finger relative to the gripper main body and the at least one second gripper finger such that a clamping force is generated, whereby an article can be held in a clamped manner by the gripper. The transmission includes a first transmission member connected to the first gripper finger, and a second transmission member mounted on the gripper main body by a transmission-member bearing arrangement having a first transmission member bearing configured to absorb the transmission-bearing reaction force that acts in a direction of the clamping force. The transmission-member bearing arrangement includes a sensor configured to sense the transmission-bearing reaction force.

A pivot bearing assembly includes a pivot pin and at least one bearing block, in which a bearing bush having a bearing bore is accommodated. The pivot pin is slidingly supported in the bearing bore. In order to create an improved pivot bearing assembly, the bearing bush has a rounded outer surface, which is inserted into a negatively rounded inner surface in order to orient the bearing bush.

A sliding contact surface-forming material, and method of making the material are disclosed, the material having minimal swelling and excellent friction-proof and wear-proof characteristics when used in moist environments such as in water, and improved in the friction-proof and wear-proof characteristics under dry friction conditions such as in the open air, particularly under oscillation conditions for testing journal. The material includes a reinforcing base impregnated with a resol-type phenolic resin having polytetrafluoroethylene resin dispersed therein. The reinforcing base is composed of a woven fabric formed by using, as each of the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyester fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun.

A contained reactive liquid transport apparatus is provided. The transport apparatus comprises a first part and a second part attachable to and detachable from one another, and a ball bearing assembly. The first and second parts each have an outer shell and extend around a common central axis to form a longitudinal chamber that can hold a contained reactive liquid. The ball bearing assembly allows the outer shells to rotate with respect to the longitudinal chamber and a contained reactive liquid held placed therein, thereby minimizing shaking or other agitation to the contained reactive liquid. In one embodiment, the transport apparatus is a combination sports ball and contained carbonated beverage transport apparatus.

A landing leg assembly for a heavy duty commercial vehicle includes a first leg member defining an interior space, a second leg member telescopingly engaging the first leg member and movable between a retracted position and an extended position with respect to the first leg member, a gear assembly at least partially located within the interior space of the first leg member and operably coupled to the second leg member and configured to receive an input from a user to move the first leg member between the retracted and extended positions, the gear assembly including a shaft member and a gear member fixed for rotation with the shaft member, and an integral, single-piece bearing member including a bore that rotatably receives the shaft member, wherein the bearing member comprises a powdered metal and is directly welded to the first leg member.

A maintenance-free bearing system having self-lubricating features, seals, grooves and slots for use in a cushion hitch assembly for a hitch pull scraper vehicle. An interconnected bearing linkage system having two or more horizontal two-axis combined journal and thrust bearings with self-lubricating liners therein, two or more vertical single-axis sleeve bearings with self-lubricating liners therein and one or more vertical thrust bearing with self-lubricating liners therein, that cooperate with one another to accommodate vertical and horizontal angular movement relative to one another.

This disclosure relates to a wear button or pad for a telescoping boom of the type comprising at least an outer boom member comprising a threaded bore therethrough for the wear pad assembly, and an inner boom member that is slidable with respect to the outer boom member. In one form, the wear pad assembly comprises a wear pad and a base, a first of which comprises a generally cylindrical body comprising a curved external side surface comprising a screw thread via which this is threadably engageable in the threaded bore, and an internally tapered expandable collet, and the second of which comprises an externally and complementarily tapered mandrel portion, wherein in use, the externally threaded part is threadably engaged in the threaded bore and expanded therein by insertion of the externally and complementarily tapered mandrel portion in the expandable collet.
